[0002] The core component of a photovoltaic device is a solar panel, which consists of multiple solar cells connected in series or parallel and is responsible for efficiently converting solar energy into electrical energy. In addition, a photovoltaic device also includes auxiliary equipment such as inverters, brackets, and cables. The inverter is responsible for converting the direct current generated by the solar panel into alternating current for use by the power grid or users, and the bracket is used to support the solar panel to ensure that it can stably receive sunlight. The working principle of the photovoltaic device is based on the photovoltaic effect, that is, when sunlight shines on a semiconductor material, photons excite the electrons in the material, forming an electric current. Solar panels use this principle to directly convert sunlight energy into electrical energy.

[0003] In order to ensure the improvement of solar energy absorption, the photovoltaic panels are designed to have a larger area. If the surface of the photovoltaic panels is contaminated by impurities, it will affect the absorption of solar energy by the photovoltaic panels. Photovoltaic panels are generally installed on higher roofs or mountain tops, which makes it very inconvenient for staff to clean the photovoltaic panels. Summary of the Invention

DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-4 As shown, a photovoltaic device with a cleaning structure of the present invention includes a mounting frame 1, a photovoltaic panel 11 is provided in the middle of the mounting frame 1, a first support frame 12 is provided at the bottom of the photovoltaic panel 11, mounting plates 13 are provided on the left and right sides of the mounting frame 1, and a second support frame 14 is provided on the lower side of the two mounting plates 13, and a slide groove 15 extending into the mounting plate 13 is provided on the upper and lower sides of the mounting frame 1, and a sliding frame 2 is slidably assembled between the two slide grooves 15, a groove 21 is provided at the bottom of the sliding frame 2, and a slide rod 22 is provided on the left and right sides of the groove 21, and a sliding part 23 is sleeved on the outer surface of the two slide rods 22, and a slide plate 24 is connected to the lower side of the two slide plates 23, and a plurality of cleaning parts 25 are provided on the lower surface of the two slide plates 24, and the two slide members 23 are jointly equipped with a driving mechanism.

[0026] The first support frame 12 can be used to fix the installation frame 1. Since the photovoltaic panel 11 is fixed in the installation frame 1, the installation of the photovoltaic panel 11 can be completed. The photovoltaic panel 11 absorbs solar energy and converts solar energy into electrical energy in conjunction with other components. When the staff needs to clean the upper surface of the photovoltaic panel 11;

[0027] The sliding frame 2 can slide toward the surface of the photovoltaic panel 11 in the slide groove 15, so the sliding frame 2 slides into the mounting frame 13 through the slide groove 2. When the sliding frame 2 slides from one side mounting plate 13 to the other side mounting plate 13, the driving mechanism starts to work, and the driving mechanism can drive the two sliding members 23 to start working at the same time, and the two sliding members 23 slide back and forth alternately. When the two sliding members 23 slide back and forth alternately, they can drive the two slide plates 24 to slide back and forth alternately. Since the lower surfaces of the two slide plates 24 are provided with a plurality of cleaning members 25, the surface of the photovoltaic panel 11 can be cleaned by the plurality of cleaning members 25 when the two slide plates 24 slide back and forth alternately. Therefore, no matter whether the sliding frame 2 slides from the left mounting plate 13 to the right mounting plate 13, or the right mounting plate 13 slides to the left mounting plate 13, the upper surface of the photovoltaic panel 11 can be cleaned by the plurality of cleaning members.

[0028] The driving mechanism includes a rack 3, and the two racks 3 are respectively arranged on the opposite side of the two sliding members 23. The groove 21 is rotatably equipped with a rotating rod 31, and the outer surface of the rotating rod 31 is equipped with a gear 32 engaged with the two racks 3. The lower end of the rotating rod 31 is equipped with a driving component.

[0029] When the sliding frame 2 slides in the sliding groove 15, the driving assembly automatically starts to work, and the driving assembly drives the rotating rod 31 to start rotating, and the rotating rod 31 drives the gear 32 to start rotating. Since the gear 32 is engaged with the two racks 3, when the gear 32 starts to rotate forward, it can drive the two racks 3 to start sliding. When the two racks 3 are working, the sliding directions of the two racks 3 are opposite, so the two racks are driven to slide back and forth alternately, which can drive the two slide plates 24 to slide back and forth.

[0030] The driving assembly includes a driving rod 33 rotatably assembled on the lower side of the groove 21. The driving rod 33 is arranged parallel to the sliding frame 2. The middle side of the driving rod 33 is rotatably assembled with a first bevel tooth 34. The lower end of the rotating rod 31 is equipped with a second bevel tooth 35 that engages with the first bevel tooth 34. Both ends of the driving rod 33 are provided with a driving wheel 36 that matches the outer surface of the photovoltaic panel 11.

[0031] When the sliding frame 2 slides in the photovoltaic panel 11, the driving wheel 36 abuts against the surface of the photovoltaic panel 11. Therefore, when the sliding frame 2 slides on the surface of the photovoltaic panel 11, the driving wheel 36 starts to rotate, and the driving wheel 36 can drive the rotating rod 31 to start rotating. Since the surface of the rotating rod 31 is provided with a second bevel tooth 35, and the driving rod 33 is provided with a first bevel tooth 34 that meshes with the second bevel tooth 35, the rotating rod 31 can be driven to start rotating.

[0032] A baffle 4 is provided on the side of the two mounting plates 13 away from each other, and a water spray pipe 41 is provided on the opposite side of the two baffles 4. A plurality of nozzles 42 are provided on the outer surface of the two water spray pipes 41. The two water spray pipes 41 are connected to a water tank 43 and are equipped with a water pump 44.

[0033] When the sliding frame 2 is located on the upper surface of one of the mounting plates 13, the water pump 44 can start working to pump out the clean water in the water tank 43 through the water spray pipe 41, and then spray it outward through a plurality of nozzles 42. This design can clean the plurality of cleaning parts 25 on the lower surface of the two slides 24 on the upper side of the mounting plate 13.

[0034] A fixed block 45 is provided on the side of the two baffles 4 away from each other, and a motor 46 is installed on the upper side of the fixed block 45. A winding wheel 47 connected to the motor 46 is provided on the lower side of the two fixed blocks 45. The outer surfaces of the two winding wheels 47 are wound with connecting wires 48, and the two connecting wires 48 are respectively connected to the left and right sides of the sliding frame 2.

[0035] When the motor 46 on one side drives the winding wheel 47 to start rotating, the connecting wire 48 can be wound. The motor 46 on one side drives the winding wheel 47 to gradually rotate in the opposite direction, canceling the winding of the connecting wire 48 on the other side, and then drives the sliding frame 2 to slide toward the side of the winding connecting wire 48. In this way, the sliding frame 2 can be effectively driven to move on the photovoltaic panel 11.

[0036] Limiting grooves are provided on the lower sides of the two slide grooves 15. Support members 51 are provided on the upper and lower sides of the sliding frame 2 and extend through the slide grooves 15 into the limiting grooves. The support members 51 are equipped with a plurality of rollers 52 located in the limiting grooves.

[0037] When the sliding frame 2 slides on the upper surface of the photovoltaic panel 1 , the support member 51 can drive the roller 52 to slide in the limiting groove, thereby effectively driving the sliding frame 2 to slide.

[0038] In the present invention, since the mounting plate 12 moves the sliding frame 2 into the mounting frame 1 through the slide groove 15, multiple mounting frames 1 can be installed between the two mounting plates 13, thereby realizing the installation of multiple photovoltaic panels 11 between the two mounting plates 12, and multiple photovoltaic panels 11 can be cleaned at the same time each time they are cleaned.

[0039] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
